Ok Tedi Mining Limited (Ok Tedi) is pleased to announce the successful deployment and commissioning of the ArcSAR Neo slope stability monitoring radar system, marking an important advance in how mine slopes are monitored and managed. Ok Tedi is the first company in the world to acquire and deploy two units of this next-generation radar technology.
Developed by IDS GeoRadar, a Hexagon company, the ArcSAR Neo is one of the most advanced slope monitoring systems available today. Its introduction demonstrates Ok Tedi's ongoing commitment to improving safety, embracing innovative technology and promoting continuous improvement in geotechnical risk management.
The new system provides a clearer view of ground conditions, allows monitoring to continue during network interruptions and can automatically adjust its position after being moved for blasting activities. These features are particularly valuable in Ok Tedi's complex mining environment, where pit operations are becoming narrower and deeper, presenting ongoing challenges.
Since commissioning, the system has demonstrated significant improvements in data quality, reliability and confidence in decision-making. Equipped with advanced processing technology and sophisticated monitoring software, the ArcSAR Neo substantially reduces common sources of interference, including atmospheric conditions and signal distortions. This has resulted in fewer false alarms and more reliable slope stability assessments.
The radar's enhanced resolution enables the detection of very small ground movements at an earlier stage, allowing potential risks to be identified early and managed proactively. This capability strengthens Ok Tedi's ability to maintain safe, productive and efficient mining operations while effectively managing geotechnical hazards.
Designed to perform in challenging environments, the ArcSAR Neo incorporates durability improvements that address historical issues such as water ingress, ensuring reliable operations in Ok Tedi's high-rainfall conditions.
The system is supported by trained and certified Ok Tedi technicians responsible for ongoing maintenance and operation in accordance with industry best practice, with additional technical support from IDS GeoRadar specialists.
The deployment of the ArcSAR Neo represents a significant advancement in Ok Tedi's slope monitoring programme. While previous ArcSAR systems have delivered dependable service for many years, the ArcSAR Neo introduces a new level of precision, reliability and operational value.
Ok Tedi will continue to assess the long-term performance of the technology under site-specific conditions and progressively integrate its outputs into the company's broader strategy. Combined training and development of technical personnel will also help maximise the benefits of this strategic investment.
The successful acquisition and deployment of the ArcSAR Neo radar system reinforces Ok Tedi's commitment to leveraging innovative technology to improve safety outcomes, enhance operational performance and support sustainable mining practices for the future.
